    I noticed today that my 94' Suburban has a humm/whistle between 45 and 55. It only happens between those speeds every other speed is quite.

    My guess would be tires...I've had them start making noise at certain speeds as they wore, and then stop making the noise a bit later.

    I've also had tires make noise at different speed ranges as the wear cycle continued (55-65, then 60-70, then 45-55).
